What issue do you have?

Hi,
First of all: thank you for a great app. I sincerely appreciate all the effort you put into this to make this app the fabulous app it is now!

I have a syncing issue with my Android phone. I'm using Joplin Server 3.3.3 on my Synology NAS and have one desktop pc and the Android phone syncing with it. The desktop pc is syncing fine and fast, but somehow the Android app is not syncing correctly anymore (after working good for months). After syncing I see the attached sync error in the Android app.

I already completely uninstalled the Android app and let it re-sync, but I'm still getting the error.

I attached the log from my Android Joplin app as well.

Can you help me out with this?

Thanks!

After almost 4 continuous hours of restarting the app and restarting the sync, it managed to complete the sync! That's great! Happy again.
Best!

Same here - A few days ago Syncing stoped working. I updated the Apps, the Server, but no Success - I can ping the server, but no success.
I tried from Windows, iOS and MacOS Clients - no Sync possible
